Abstract
A method and system for utilizing electromagnetic energy to inhibit, prevent, reverse, or alter the formation of rust or scale on various liquid contacting surfaces is disclosed. An electromagnetic signal at a frequency related to the energy absorption/emission characteristics of the liquid being treated are directed into the liquid. The frequency of the treatment signal, preferably between 0.1 KHz and 1000 MHz, may be changed if the absorption/emission profile of the liquid changes during treatment.
